The Crusades were a series of religious wars called by the Pope in the 11th century to recapture the Holy Land from Muslim rule. Jerusalem was an important religious site for Christianity, Islam, and Judaism, leading to conflict over control of the city. Pope Urban II launched the First Crusade in 1095 after Christian pilgrims to Jerusalem were attacked by Seljuk Turks. The Crusaders succeeded in taking Jerusalem in 1099 but failed to maintain permanent control of the city, which was recaptured by Saladin in 1187. The Crusades ultimately did not achieve their goal of permanently securing Christian control over the Holy Land and led to continued conflict between Christians and Muslims over Jerusalem.
